If you get into the WSSMs try and find some Federal brass, as it is thinner than the Winchester/Olin brass and doesn't need as much attention. I have some 25 WSSM cases that have been loaded over 8x with only about a 2% case failure rate.

For a few years, the 25 WSSM was my primary pdog and deer cartridge, but I've moved on to other/different cartridge/rifle combinations.
